Cool box operation
This is a question to any of you who use a 12 volt cool box in the boot of your car.
Prior to our annual migration to sunny-ish Devon, I decided to put our new cool-box to the test and ran it for 24 hours. To be frank, the resultant temperature was something of a disappointment. The interior was best described as "luke-cool" so to speak. Certainly not what I'd describe as cold, as in, a suitable temperature to store cold drinks, salad, etc. I was wondering what other members opinions might be. Does one perhaps, put frozen chiller blocks in overnight prior to assist in temperature reduction and then freshly frozen chiller blocks on the day of travel, along with the food and drinks? Your thoughts most welcome please |

You ran it for twenty four hours?! The noise mine made drove me mad! I guess though that if you put ice packs and food and drinks that are already cold it may maintain the temperature. When I go camping I always use a normal cool box and put in about six kilograms of ice and that makes canned drinks super chilled so I suppose this method could also be used if you put food in big sandwich bags. I've done that. Ususally after 12 to 15 hours its mainly still ice.

Much the same experience so tend to...... put frozen chiller blocks in overnight prior to assist in temperature reduction and then freshly frozen chiller blocks on the day of travel, along with the food and drinks

Yes the standard ones have such a small Peltier module that they can at best keep things coolish. Getting things cold in the first place isn't going to happen
You need a better one with a bigger module, or a compressor or chemical one to work any better. |

It's best not to keep it in the boot. We leave ours on the back seat and it keeps stuff lovely and cold. One of the good things about it is, that it's got a battery sensor on it that detects when the battery drops to a certain voltage and turns itself off to save flattening the battery. One of the best things I've bought from Halfrauds.

This is the one we use. Even had ice forming in it while we were away camping in July. Only downside to it is water dripping from the condensing unit. easily solved though by putting a small tupperware box under it to catch any drips.

I have one in the boot cost about £30 from Argos and would not be without it. Keeps drinks etc. lovely and chilled. I bought it to use for the Cosford meet. I also use it if I pop out lunchtime from work & get some chilled products for tea. I guess it's down to the effectiveness of the box and it's quality. Also as the instructions say don't pack the box jammed full air must be allowed to circulate through the stuff you have in there. :lol:

The cool box needs to dissipate heat in order to provide the cooling. The boot of the car will be warm and get warmer from the heat given off by the box thereby reducing the cooling effect - needs to be kept somewhere where the heat is less, i.e. inside the car especially with the a/c on.
